CD-R Drives FAQ


Drive is not recognized.

When installing CD-R drive in the PC, the Device Manager does not recognize the drive. Is the drive broken?

First, try the following. If the problem persists after following these steps there may be something wrong with your drive.

1. Ensure if your SCSI host adapter is correctly recognized from a SCSI utilities program, such as EZ-SCSI. In case not being correctly recognized, please contact your SCSI adapter's manufacturer.
2. Check your SCSI cable if there is something wrong, for example,
  • Whether SCSI pins bend.
  • Whether it made length of SCSI cable standards.
3. Set a terminator at the end of SCSI line.
4. Ensure each SCSI device has a unique SCSI ID. If there are same ID in a SCSI line, it may cause some problem. Especially, most Macintosh have SCSI device and some ID number is already used.
5. Ensure to put a plug in a socket. If not, it does not turn on a power well.

After updating Windows 3.1 to Windows95, it appears the message like unknown device and RS-9200CD is not recognized. What is wrong?

As RS-9200CD is the model for Windows 3.1 only, we do not provide any drivers for Windows 95. In that case, please purchase another writing software program, which support both your OS and RS-9200CD. It appears the message under Windows 95 for the reason that the device type of RS-9200CD is not CD-ROM.

Cannot recognize a CD-R disc.

When I insert a CD-R disc into the drive, the disc is automatically ejected. Is there a problem with the drive?

Please test using other discs like Audio CD or stamps CD-ROM. If the other discs are recognized the problem appears to be with the first disc. Should all the discs be ejected then there may be a problem with the drive.

Writing error

During the writing process a Buffer under-run error occurred. Is there something wrong with the drive?

Usually this error appears when there is a problem with the data transfer. In the majority of these cases this is a system problem and rarely is it a drive problem. First try to defragment your HDD. In the case where a CD-ROM drive was used as a source device, modify the recording method by creating image files on the HDD before recording. Alternatively reduce the writing speed.


After installing the CD-RW drive the PC often freezes by just moving the mouse. Is there something wrong with the drive?

2. The data transfer rate of SCSI adapter may cause this problem. Check the configuration of the adapter.
